WIRE I-IEDDLE-EYE FOR LOOMS.

Specification of Letters Patent No. 10,623, dated March 7, 1854.

To all whom it may concern.

Be it known that I, THOMAS GLEGG, of North Andover, in the county of Essex and State of Massachusetts, have invented a new and useful Improvement in the Manufacture of Metallic WVire Eyes for I-Iarnesses for Looms; and I do hereby declare that the same is fully described and represented in the following specification and the accompanying drawings, figures, letters, and references thereof.

Of the said drawings, Figure 1, denotes on an enlarged scale, a metallic heddle eye made in my improved manner. Fig. V2, is an edge view, and Fig. 3, is a longitudinal section of it.

In the manufacture of heddles from wire, either one or both extremities of the eye or opening for the reception of a warp thread, have been formed by simply twisting together the two pieces of round wire. When the eyes are so made, it has been found Very difficult. if not impossible to use them in the weaving of fine fabrics, they being only useful in the manufacture of those made from coarse yarn. The occasion of the difficulty is the catching of the warps in the twist of the wires. It will readily be seen that when the warp thread is lifted upward by the heddle, considerable strain is produced on it, which strain tends to cause the thread to pass into the twist and between the two wires, and to become there caught and held so firmly as to be productive of injurious consequences.

My improvement consists in so compressing the two wires at the top and bottom of the eye as to flatten them on one another and bring them to or about the thickness of a single wire, when they are laterally spread out. This compression might be produced by pressure between jaws or. by a hammer.

In the drawings, a, I), represent the two wires or sides of the eye of the opening 0, twisted together, and afterward flattened or compressed together as seen at (Z, c. This compression of them brings them into such close connection and imparts to them such a pecullarshape at top and bottom of the eye openlng as entirely prevents the'catching of the warp thread as described, and

thereby renders this eye, or a heddle made with such, capable of being used in the weaving of fine goods. The eye represented in the drawings is one which in the formation of a harness for a loom is to be connected with strings or cords run through small 9, made at the extremities of the twists. A heddle so made isfar preferable to one made entirely of wire. It is common to make a harness of cords having metallic eyes, fixed in them, but as such eyes have been usually constructed, their cost, and the difliculty of making them smooth enough has been a serious objection to their use.

The eye as made by me of round wires twisted together and subsequently compressed on one another and flattened as described, not only can be manufactured at much .less expense, than most other metallic eyes in use for heddles, but is far superior to them, and is perfectly adapted either for fine or coarse weaving.

I do not claim a loom harness metallic eye or eyelet made by being stamped out of a piece of metal, nor do I claim a metallic eye or heddle formed of round wire or wires twisted together; but

. What I do claim as an improvement or improved manufacture is A loomharness metallic eye, made of round wire or wires twisted together and compressed and flattened in the twist of its wires and directly at the top and bottom of its warp thread opening, substantially in manner and for the purpose as described.

In testimony whereof I have hereto. set.

my signature this tenth day of February A. D. 1853.
